Yes.
The "Intended Use" section explicitly states that the device is "intended to provide adjunctive treatment" and "temporarily reduce and/or manage pain and temporarily relieve acute procedural anxiety."
No
The device is intended to provide adjunctive treatment for pain and anxiety relief during needle procedures, not to diagnose medical conditions.
No
The device description explicitly states that Smileyscope is an immersive virtual reality (VR) device consisting of both Hardware and Software components.
Based on the provided information, the Smileyscope System's Therapy Mode is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are devices used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
- Smileyscope's Function: The Smileyscope System is a virtual reality system that provides adjunctive treatment based on behavioral methods to reduce pain and anxiety during needle procedures. It interacts directly with the patient through visual and auditory stimuli, not by analyzing biological samples.
The description clearly states its intended use is for providing a therapeutic intervention, not for analyzing biological specimens for diagnostic purposes.
N/A
Intended Use / Indications for Use
The Smileyscope System's Therapy Mode is a prescription-use immersive virtual reality system intended to provide adjunctive treatment based on guided relaxation and other evidence-based behavioral methods for patients aged 4-11 years who can cooperate and interact with the device at a developmentally appropriate level. The Smileyscope Therapy Mode is intended to temporarily reduce and/or manage pain and temporarily relieve acute procedural anxiety associated with needle procedures (e.g., venipuncture, IV placement, vaccination, port access, subcutaneous injections). The device is not intended to treat anxiety disorders or specific phobias (e.g. trypanophobia).

Device Description
Smileyscope is an immersive virtual reality (VR) device, consisting of Hardware and Software components. In Smileyscope Therapy mode, the device delivers 3-dimensional virtual reality treatment based on guided relaxation and other evidence-based behavioral methods to temporarily reduce pain and temporarily relieve acute procedural anxiety in individuals undergoing needle procedures. This prescription-use device uses pre-loaded software on a proprietary hardware and software platform to deliver treatment. The Smileyscope device is supplied with a USB charger and USB cable to facilitate charging.
The physical device consists of two major subcomponents: a detachable mobile interface, or "Faceplate", that clinicians can interact with via a touchscreen. The Faceplate contains an embedded mobile phone (Google Pixel 3) running Smileyscope software. Second, a head-mounted virtual reality headset, or "Main Body". The Main Body is placed on the patient's head and positioned via the Adjustable Head Strap. The Faceplate attaches to the Main Body via magnets. Lenses in the Main Body permit the display of virtual reality.
Clinicians use the Smileyscope System to administer the Smileyscope Therapy mode. In this software mode, the Smileyscope System provides evidence-based virtual reality behavioral therapy during a needle procedure. While the patient undergoes the needle procedure in the real world, the Smileyscope Therapy Mode provides an interactive "underwater adventure" virtual reality experience. The virtual reality experience contains evidence-based guided relaxation and behavioral techniques designed to temporarily reduce pain and temporarily relieve acute procedural anxiety during needle procedures. The underwater adventure can be configured by the Clinician to last 1-10 minutes. Audio cues are provided throughout the virtual reality experience which allow the clinician to synchronize the procedure with common needle-based procedures. However, precise timing is not necessary. The experience loops if the procedure takes longer than anticipated. The software has been designed to avoid common adverse effects associated with virtual reality. For example it contains minimal motion (to reduce motion sickness) and objects are positioned at optimal distances in the virtual environment so as to avoid virtual reality disequilibrium.

Device Description:
Smileyscope is an immersive virtual reality (VR) device, consisting of Hardware and Software components. In Smileyscope Therapy mode, the device delivers 3-dimensional virtual reality treatment based on guided relaxation and other evidence-based behavioral methods to temporarily reduce pain and temporarily relieve acute procedural anxiety in individuals undergoing needle procedures. This prescription-use device uses pre-loaded software on a proprietary hardware and software platform to deliver treatment. The Smileyscope device is supplied with a USB charger and USB cable to facilitate charging.
Hardware:
The physical device consists of two major subcomponents (Figure 1 and Figure 2).
First, a detachable mobile interface, or "Faceplate", that clinicians can interact with via a touchscreen. The Faceplate contains an embedded mobile phone (Google Pixel 3) running Smileyscope software. Second, a head-mounted virtual reality headset, or "Main Body". The Main Body is placed on the patient's head and positioned via the Adjustable Head Strap. The Faceplate attaches to the Main Body via magnets (Figure 2, final step in Table 1). Lenses in the Main Body permit the display of virtual reality.
Image /page/4/Figure/5 description: The image shows a medical device with three labeled parts: faceplate, main body, and adjustable head strap. The faceplate has a screen that displays the word "Therapy" and options for age and session length. The main body is white and curved, and the adjustable head strap is teal and appears to be made of a flexible material. The device is designed to be worn on the head.

Software:
Clinicians use the Smileyscope System to administer the Smileyscope Therapy mode. In this software mode, the Smileyscope System provides evidence-based virtual reality behavioral therapy during a needle procedure.
While the patient undergoes the needle procedure in the real world, the Smileyscope Therapy Mode provides an interactive "underwater adventure" virtual reality experience. The virtual reality experience contains evidence-based guided relaxation and behavioral techniques designed to temporarily reduce pain and temporarily relieve acute procedural anxiety during needle procedures.
The underwater adventure can be configured by the Clinician to last 1-10 minutes. Audio cues are provided throughout the virtual reality experience which allow the clinician to synchronize the procedure with common needle-based procedures. However, precise timing is not necessary. The experience loops if the procedure takes longer than anticipated. The workflow is elaborated in Table 1.
The software has been designed to avoid common adverse effects associated with virtual reality. For example it contains minimal motion (to reduce motion sickness) and objects are positioned at optimal distances in the virtual environment so as to avoid virtual reality disequilibrium.

Clinical Performance Testing
14
Smileyscope Therapy Mode has undergone Clinical Performance Testing. Smileyscope Therapy Mode was tested in two independent randomized clinical studies, which have been peer-reviewed and published in the Journal of Pediatrics2. Briefly, in both studies Smileyscope Therapy Mode, consistently demonstrated benefits for the primary endpoint of child-rated pain, and substantially reduced the secondary endpoint of procedural anxiety. The pre-specified primary safety and effectiveness endpoints were met in both studies, which were conducted outside of the United States only, in comparable population(s). These are summarized in Table 3 below. Overall, Smileyscope Therapy Mode was safe, with no significant adverse effects, specifically with regards to the Identified Risks to Health from the Primary Predicate's Special Controls. Adverse effects were mild (nausea, dizziness, headache, vomiting) and were self-limiting; they did not require pharmacotherapy.

Conclusion:
Smileyscope Therapy Mode and the predicate device have intended use, have different technological characteristics, with appropriate clinical and scientific data that demonstrates the device is as safe and effective as a legally marketed device, and there are no different questions of safety and effectiveness than the predicate. The conclusions drawn from the nonclinical and clinical tests that demonstrate that the device is as safe, as effective, and performs as well as the Primary Predicate Device.
